Django模塊無差錯「類型錯誤：‘XXX’是這個函數

Question

無效關鍵字參數我得到的錯誤：

TypeError: 'person' is an invalid keyword argument for this function 

我的模式是：

class Investment(models.Model): 
company = models.ManyToManyField("Company", related_name ="Investments_company") 
financial_org = models.ManyToManyField("Financial_org", related_name ="Investments_financial_org") 
person = models.ManyToManyField("Person", related_name ="Investments_person") 

我的測試（即給出了錯誤）：

investment1 = Investment(company = [], financial_org = financial1, person = []) 

Answer 1

1. 實例化您的MO德爾，沒有多對多investment1 = Investment()

2. 保存模型，investment1.save()

3. 許多加入許多，有several ways to do it像或investment1.person.create(name='foo')

您不得使用ManyToMany關係，直到保存模型，這是b因爲ManyToMany關係表中的行需要關係兩邊的模型的pk。
